Solve x and y : x+4/2 =3,2x +y=7.
Answers
Answer:
Step-by-step explanation:
X+4/2=3, 2x+y=7
X+4/2=3
2x+4/2=3
2x+4=3×2
2x+4=6
2x=6-4
2x=2
X=2/2
X=1
Substituting, value of x=1
2x+y=7
2(1) +y=7
Y=7-2
Y=5
Hence,
X=1 & y=5
Answer :
›»› The value of x is 1.
›»› The value of y is 5.
Given :
- x + 4/2 = 3.
- 2x + y = 7.
To Find :
- The value of x = ?
- The value of y = ?
Solution :
→ x + 4/2 = 3
Reduce the fraction,
→ x + 2 = 3
Move the constant to right side and change the sign,
→ x = 3 - 1
Subtract 2 from 3,
→ x = 1
║Hence, the value of x is 1.║
Verification :
→ x + 4/2 = 3
→ 1 + 4/2 = 3
→ 1 + 2 = 3
→ 3 = 3
Here, LHS = RHS
Hence Verified !
━━━━━━━━━━━━━━━━
→ 2x + y = 7.
Put the value of x in 2x + y = 7,
→ 2 * 1 + y = 7
Multiply any number by 1 does not change the value,
→ 2 + y = 7
Organize the expression,
→ y + 2 = 7
Move the constant to the right side and change the sign,
→ y = 7 - 2
Subtract 2 from 7,
→ y = 5
║Hence, the value of y is 5.║
Verification :
→ 2x + y = 7
→ 2 * 1 + 5 = 7
→ 2 + 5 = 7
→ 7 = 7
Here, LHS = RHS
Hence Verified !
║Hence, the value of x is 1 and the value of y is 5.║
